Randomized Controlled Trial Comparative StudyRandomized trial of HTK versus warm blood cardioplegia for right ventricular protection in mitral surgery.
To clarify the reliability of the one-shot histidine-tryptophane-ketoglutarate (HTK) cardioplegia for right ventricular (RV) myocardial protection during mitral surgery, in patients with or without pre-operative RV dysfunction. ⋯ The one shot HTK solution offers inferior RV protection compared with WBC, mainly in patients with depressed pre-operative RV function. When adopting HTK cardioplegia the addition of topical cooling is strongly advised.

Randomized Controlled TrialRetransfusion of cardiotomy suction blood impairs haemostasis: ex vivo and in vivo studies.
Cardiotomy suction blood in volumes corresponding to 10-20% of the systemic blood volume is retransfused during cardiopulmonary bypass. We hypothesized that retransfusion of unwashed cardiotomy suction blood influences coagulation and platelet function. ⋯ The ex vivo results suggest that addition of unwashed cardiotomy suction blood in clinically relevant volumes impairs systemic haemostasis. Retransfusion of smaller volumes in vivo has no or limited impact. Avoiding retransfusion of larger amounts of unwashed cardiotomy suction may improve postoperative haemostasis.
